Operations and maintenance systems and methods employing sensor-less digital twins

Abstract

An operations and maintenance (O&M) system, and related method, for a plurality of unique objects characterized by distinct digital twins. The O&M system includes: a database subsystem for storing at least first and second distinct digital twins for each of the plurality of unique objects; at least one of the digital twins has an identifier that uniquely associates it with one of the plurality of unique objects and defines a unique virtual representation thereof. The system further includes a virtual sensor subsystem operative to emulate operational data for ones of the plurality of objects; the virtual sensor subsystem is not dependent on sensors physically associated with ones of the plurality of unique objects. A digital twin comparison subsystem is operative to compare outputs of the at least first and second distinct digital twins for each of the plurality of unique objects; the output of at least one of the first and second digital twins is a function of the emulated operational data for its associated object, and the O&M system makes an operational or maintenance decision with respect to an object as a function of the comparison.
